Description
Technical Field
[0001] The present application relates to the technical field of textiles, and in particular to a functional bandage having both efficient moisture absorption and quick-drying properties and structural stability and a preparation method thereof. Background Art
[0002] In sports and medical settings, textiles that come into contact with the skin need to possess excellent water absorption properties to absorb sweat produced during exercise or exudate from the skin surface during medical procedures. This not only improves user comfort but also enhances athletic performance in sports and, in the medical field, prolongs treatment time and reduces the incidence of complications such as infection. However, existing absorbent textile materials have many drawbacks: while traditional hydrophilic short-hair materials have strong water absorption capacity, they also retain water, making it difficult for absorbed water to evaporate quickly; single hydrophobic fibers cannot effectively absorb sweat; and some multi-layer composite materials, while attempting to achieve both water absorption and breathability, often result in thick and heavy products with poor breathability. After prolonged use, the humid environment can easily cause skin problems, affecting the user experience and health. Summary of the Invention

The bandage is made of moisture-absorbing and quick-drying yarn. The raw material of the moisture-absorbing and quick-drying yarn includes hollow hydrophobic hollow zigzag filaments. The outer peripheral wall of the hydrophobic hollow zigzag filaments is provided with a protrusion. The outer peripheral wall of the hydrophobic hollow zigzag filaments and the protrusion are both provided with hydrophilic short fluff.
[0005] By adopting the above technical solution, the hydrophobic hollow zigzag filament adopts a hollow structure, which not only makes the material itself lightweight, but also has a good ventilation effect. The setting of the raised part increases the surface area of the moisture-absorbing quick-drying yarn, so that more hydrophilic short hairs can be attached, and can form ventilation channels on the surface of the wet quick-drying yarn, further improving the air permeability; the hydrophilic short hairs on the moisture-absorbing quick-drying yarn have a good water absorption effect, so the resulting bandage has both good water absorption and air permeability.
[0006] In a specific embodiment, the hydrophobic hollow zigzag filaments have a hollow ratio of 30-60%.
[0007] By adopting the above technical solution, the hollow ratio of the hydrophobic hollow zigzag filaments is further limited, so that the hydrophobic hollow zigzag filaments have both good strength and good ventilation and are light.
[0008] In a specific embodiment, the number of the protrusions is 8-12, and the protrusions are evenly distributed along the circumference of the hydrophobic hollow zigzag filament; and the protrusions are provided with a fillet of 30-60°.
[0009] By adopting the above technical solution, the number of raised parts and the angle of the fillet are further limited, so that the product has both a certain rigidity and good softness.
[0010] In a specific embodiment, the density of the hydrophilic short hairs on the moisture-absorbing and quick-drying yarn is 200-500 pieces / cm 2 , and the length is 0.1-1mm.
[0011] By adopting the above technical solution, the density and length of the hydrophilic short pile are further limited, so that the moisture-absorbing and quick-drying yarn has a better moisture-absorbing effect.
[0012] In a specific embodiment, the raw material of the hydrophilic short fluff includes one or both of viscose fiber and combed cotton fiber.
[0013] In a specific embodiment, the raw materials of the hydrophobic hollow zigzag filaments include one or more of polyester, nylon, and nano-titanium dioxide.
[0014] In a second aspect, the present application provides a method for preparing a functional bandage having both efficient moisture absorption and quick-drying properties and structural stability, which adopts the following technical solution: A method for preparing a functional bandage having both efficient moisture absorption and quick-drying properties and structural stability comprises the following steps: Preparation of hydrophobic hollow zigzag filaments: melt-spinning the raw materials of the hydrophobic hollow zigzag filaments to obtain hollow hydrophobic hollow zigzag filaments, wherein a convex portion is integrally formed on the outer peripheral wall of the hydrophobic hollow zigzag filaments; Electrostatic flocking: First, the raw material of hydrophilic short pile is cut into short pile, and then the hydrophobic hollow zigzag filaments are electrostatically flocked to form hydrophilic short pile on the peripheral wall and protrusion of the hydrophobic hollow zigzag filaments, and then dried to obtain a crude product; Pre-shrinkage treatment: The crude product is pre-shrinked to obtain a moisture-absorbing quick-drying yarn; Weaving: The moisture-absorbing and quick-drying yarn is woven to obtain a functional bandage with both efficient moisture-absorbing and quick-drying properties and structural stability.
[0015] By adopting the above technical solution, hydrophobic hollow zigzag filaments are first prepared, and then electrostatic flocking is performed to load hydrophilic short hairs on the hydrophobic hollow zigzag filaments. The yarn is dried and pre-shrunk to obtain moisture-absorbing and quick-drying yarn, and finally woven to obtain a functional bandage with both efficient moisture-absorbing and quick-drying properties and structural stability.
[0016] In a specific embodiment, in the electrostatic flocking step, the hydrophobic hollow zigzag filaments are electrostatically flocked under a tension of 5-10N, with a flocking voltage of 30-50kV and a drying temperature of 80-100°C.
[0017] By adopting the above technical solution, the hydrophobic hollow zigzag filaments are further limited to be electrostatically flocked under a tension of 5-10N and a flocking voltage of 30-50kV, so that the hairs are evenly and firmly attached to the surface of the filaments.
[0018] In a specific embodiment, the pre-shrinkage treatment step is: heat-treating the crude product at 120-150° C. for 10-30 seconds to obtain a moisture-absorbing quick-drying yarn.
[0019] By adopting the above technical solution, the crude product is heat-treated, and micron-level wrinkles are formed on the surface of the crude product with a wrinkle depth of 5-20μm, which increases the contact area with moisture and air and further improves the air permeability and quick-drying performance of the fabric.

The hydrophobic hollow zigzag filaments in this application adopt a hollow structure, which not only makes the material itself lightweight but also has good ventilation effect. The provision of the raised portion not only increases the surface area of the moisture-absorbing quick-drying yarn, thereby allowing more hydrophilic short hairs to attach, but also forms ventilation channels on the surface of the wet quick-drying yarn, further improving the breathability. The hydrophilic short hairs on the moisture-absorbing quick-drying yarn have a good water absorption effect, so the resulting bandage has good water absorption and breathability. 2. This application further limits the number of raised portions and the angle of the rounded corners, so that the product has both a certain degree of rigidity and good softness; 3. The method of the present application first prepares hydrophobic hollow zigzag filaments, then performs electrostatic flocking to load hydrophilic short hairs on the hydrophobic hollow zigzag filaments, dries, and pre-shrunk to obtain moisture-absorbing and quick-drying yarns, which are finally woven to obtain a functional bandage with both efficient moisture-absorbing and quick-drying properties and structural stability.

The voltage is 40kV, the flocking time is 30s, and the density is 350 pieces / cm 2 , drying at 90°C, and then releasing the tension to obtain a crude product; wherein the raw material of the hydrophilic short fluff 3 is viscose fiber with a fineness of 1.2 dtex; Pre-shrinkage treatment: the crude product was treated with hot air at 120°C for 15s, with a shrinkage rate of 5%, to obtain a moisture-absorbing quick-drying yarn; Weaving: The moisture-absorbing and quick-drying yarn is woven to obtain a functional bandage.
[0041] Performance testing Moisture absorption and quick-drying properties: The water absorption rate of the bandages in each embodiment and comparative example was tested in accordance with GB / T21655.1. The higher the water absorption rate, the better the hygroscopicity of the bandage. The bandages after absorbing moisture were naturally evaporated and dried at 37°C and RH65%.

The hydrophobic hollow zigzag filaments 1 in the moisture absorption and quick-drying yarn adopt a hollow structure, which not only makes the material itself lightweight, but also has a better ventilation effect.

[0045] Combining Example 1, Example 4 and Example 5, it can be seen that when performing electrostatic flocking, the flocking conditions in Example 1 are preferred, and the resulting bandage not only has good water absorption but also good quick-drying properties.
[0046] In combination with Example 1 and Example 6, it can be seen that when preparing the hydrophobic hollow zigzag filaments 1, nano-titanium dioxide is added to the raw materials, which improves the UV resistance of the hydrophobic hollow zigzag filaments 1, so that the obtained bandage can maintain structural stability when used outdoors; when performing electrostatic flocking, a composite raw material composed of viscose fiber and combed cotton fiber is used, so that the obtained bandage has good stable and quick-drying performance after repeated use.
